Flashcards in Intestinal Failure Deck (17):
1

Define intestinal failure.

Inability to maintain adequate nutrition or fluid status via intestines.

Inability to maintain protein, electrolyte, fluid, micronutrient levels

2

List some reasons that might cause intestinal failure

obstruction, dysmotility, post op, congenital

3

Which of the 3 types of intestinal failure are acute or chronic?

1. Acute- Type 1, 2
2. Chronic - Type 3

4

What is Type 1 intestinal failure?

Self limiting, Short term. Either post-op or paralytic ileus.

5

What is Type 2 intestinal failure?

Prolonged, associated with sepsis, metabolic or surgical complications.

6

What is Type 3 intestinal failure?

Long term, parenteral nutrition needed

7

What is the management of Type 1 failure?

1. Replace fluids, Correct electrolytes
2. Parenteral nutrition- if unable to tolerate oral fluids./food
3. Acid suppression drugs
4. Allow some enteral feeding

8

What is parenteral feeding?

IV admission of nutrients. May be supplemental or only source of nutrition

9

What are the two types of access used in parenteral feeding?

1. Central- central catheters used in tunnelled subclavian vein central lines

2. Peripheral- central catheters used in peripheral veins.

10

What are some complications of using parenteral feeding? (5)

1. Sepsis
2. SVC thrombosis
3. Nutritional toxicity
4. Psycho-social
5. Line leakage/fracture

11

Type 2 intestinal failure patients often develop this as a result of _

Sepsis.
Also seen in perioperative feeding complications

Parenteral +/- enteral feeding

12

What are the management options in Type 3 failure? (4)

1. Home parenteral nutrition
2. Intestinal transplantation
3. Teduglutide treatment
4. Bowel lengthening

13

Two methods of bowel lengthening?

1. Longitudinal lengthening- splitting the bowel into before joining the longitudinal lengths together.
Increases length but reduced radius

2. Serial transverse enteroplasty- Little cuts are made in a zig zag pattern along the bowel, increasing amount of absorption

14

What is the choice of treatment in chronic intestinal failure?

Home parenteral nutrition

15

What is short bowel syndrome?

Length of small bowel insufficient to meet nutritional needs without artificial support

Has to be less than 200cm of small bowel
Normal length- 250-850

16

Small bowel transplantation is mostly successful. T/F?

True

17

Main complication of small bowel transplant? (2)

1. Liver failure
2. Loss of venous access
